About Viral Hepatitis

Factsheet on Hep CThe term "hepatitis" means inflammation of the liver. Viral hepatitis refers to a group of viral infections that affect the liver. The most common types of viral hepatitis are hepatitis A, hepatitis B and hepatitis C.

Nationwide, an estimated 50% of people living with chronic viral hepatitis are not aware of their infection. Viral hepatitis is sometimes called a "silent killer" because chronic hepatitis B and hepatitis C infections can progress without symptoms for years, with a person learning about their infection after they have moderate to advanced liver disease.

Hepatitis A and hepatitis B can be prevented with vaccination. While there is currently no vaccine for hepatitis C, new, highly effective treatments can cure more than 90% of people with chronic hepatitis C infections, and successful treatment can slow or stop liver disease progression.

The only way to know if a person has viral hepatitis is through testing.

Request the Test

People with health insurance who want to be screened for hepatitis C should see their health care provider and request a hepatitis C screening test.

Studies show that an estimated 50% of persons living with HCV have not been diagnosed, suggesting that as many as 95,000 Oregonians could be infected. It is generally accepted that 5 to 25% of those infected will develop cirrhosis 20 to 30 years later, and 1 to 5 % will develop end-stage liver disease or cancer.
